Anthony Joshua's promoter Eddie Hearn has revealed that Cardiff is the frontrunner to host the world heavyweight champion's next title defence later this year.

The Principality Stadium appeared to have missed out on hosting the IBF and WBA world champion's next bout, with the rematch against Wladimir Klitschko heading to Las Vegas.

But Klitschko dropped a bombshell by announcing his retirement from boxing, leaving the Joshua fight dead in the water.

There was an agreement in place with the IBF that if the Brit didn't fight Klitschko, he would move on to face Kubrat Pulev, who is the mandatory challenger, and Cardiff is now firmly back in the picture.
